HARRY R. BRINSER, OF MIDDLETOWN, PENNSYLVANIA.

GRAIN-DRIER.

eeegroo.

To all whom it may concern:

Be it known that I, HARRY It. BRINSER, a citizen of the United States,residing at Middletown, in the county of Dauphin and State ofPennsylvania, have invented certain new and useful Improvements inGrain-Driers, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention is an improved drier for drying grain, nuts and othercommodities, and consists in the construction, combination andarrangement of devices hereinafter described and claimed.

V The object of my invention is to provide a cheap, simple and easilyoperated device of this character which is not likely to get out oforder, is very strong and durable, and is provided with means to preventthe grain from adhering to the drying cylinder, and becoming burned andis also provided with means to prevent smoke or other products ofcombustion from the furnace or fire box from entering the dryingcylinder, and injuring the grain. V V V In the accompanyingdrawingsFigure 1 is a vertical longitudinal sectional view of a drierconstructed in accordance with-my invention. Fig. 2 is partly a frontelevation of the same, and partly a transverse sectional view on theplane indicated by the line a-a of Fig. 1.

In accordance with my invention, I provide a casing 1, which is hereshown as of rectangular form and comprises a lower or body member 2, anda cover 3 which forms the upper member of the casing and is re movablefrom the lower or body member, the latter being provided at its cornerswith upright guides 4, which serve to retain the cover in place, and yetpermit the cover to be readily removed from the body or lower member ofthe casing, at will.

The casing is preferably constructed of sheet or plate metal, but may bemade of any suitable material. The lower member or body 2 of the casingis provided at one side with a fire door 5, and is also here shown asprovided with a suitable grate 6 on which a fire may be made. a

Within the scope of my invention the casing may be provided with anysuitable heating means and I would have it understood that I am notlimited as to this particular.

The cover of the casing is shown as pro Specification of Letters Patent.

vided with a flue 7. The front end of the body of the casing is providedwith a graindischarge opening 8, and with a slide door 9, to cover oropen the same, the said slide door being mounted in suitable guide-ways10. The front end of the cover or upper member of the casing is providedwith a grain feed opening 11, and a slide door12 for the same, the saidslide door being mounted in guide-ways 13.

The grain cylinder 1 1 is provided with a shaft 15which has its bearingsat the front and rear ends of the casing. The cylinder is secured to theshaft by any suitable means. Suitable means, such for instance as acrank handle 16 is provided for rotating the shaft, and hence also thegrain cylinder. Any suitable means may be employed for this purpose. Therear end of the grain cylinder is closed as at 17. Its front end is openas'at 18, and is provided with crossed bars 19 which support the saidopen end of the grain cylinder on the shaft. Near its front end thegrain cylinder is provided with an annular circumferential guard flange20. The front walls of the lower and upper members of the casing areprovided on their inner sides with a semi-circular recess 21, in whichthe front end of the cylinder is disposed, and the guard flange 20 ofthe cylinder bears against the inner surfaces of the said walls, andhence serves to prevent smoke or other products of combustion fromentering the front end of the cylinder, and injuring the contentsthereof. It will be observed that the cylinder extends directly over andabove the grate so that the cylinder becomes heated, and hence the grainor other contents of the cylinder becomes heated while the cylinder isbeing revolved.

The shaft is provided with a conveying screw or worm 22 which extendsfrom the front end of the cylinder nearly to the rear end thereof. Whenthe cylinder is revolved in the direction indicated by the arrow in Fig.2, the said conveyer worm serves to move the grain in the cylinder fromthe front end thereof and toward its rear or inner end. The cylinder isalso provided on its inner side with obliquely disposed flights 23 whichserve to move the grain from the inner end of the cylinder to the frontopen end thereof, so that as the cylinder revolves, the grain which isin the vicinity of the conveyer worm is moved toward the rear end of thecylinder, and the grain which is on the bottom of the cylinder is movedtoward the front end thereof, and hence the grain is kept in constantcirculation and is prevented from adhering to the cylinder at any pointand becoming burned, and moreover, the grain becomes heated and dried toa uniform extent at all points in the cylinder.

Assuming that the door 9 is closed the grain or other commodity to bedried is put into the drying cylinder through the opening 11, afteropening the door 12, and when the cylinder has been filled to thedesired extent and so as to cover its shaft, and the conveyor wormthereon, the said door 12 is then closed, and the cylinder is caused torotate. A vent flue 24: is preferably .provided to discharge the vaporsfrom the interior of the cylinder and is here shown as attached to thefront wall of the upper member 3 of the casing. After the grain has beendried and heated, a suflicient length of time, the door 9 is opened andthe continued rotation of the cylinder causes the flights therein todischarge all of the grain from the cylinder out through the opening 8.

I claim The herein described grain drier comprising a casing having alower member and an upper member. removable from the lower member, theformer being provided with heating means, the latter being provided witha flue and the said lower and upper members being provided at one end ofthe casing on their inner sides with a circular recess, one half ofwhich is formed in each of said members, the upper member being providedat the said end with an inlet opening and a closure therefor and thelower member being also provided at the said end with a dischargeopening and a closure therefor; a grain cylinder mounted for rotation insaid casing, having an open end disposed in said circular opening of thecasing and further provided with an outwardly extending flange bearingagainst the recessed end of the casing, the said cylinder being providedwith a supporting shaft which has its bearings at the joints between thelower and upper members of the casing at the ends thereof, the saidshaft being provided with a conveyer worm to move grain inwardly in thecylinder and the latter being provided at its periphery with flights tomove the grain toward the open end of the cylinder.

In testimony whereof I hereunto afflx my signature in the presence oftwo witnesses.
